  1. We also derived the relationship between the radial local density distribution and the observed line integral density distribution by fourier integral transform. on this basis, the density inversion calculation is realized through fft method and is independent of abel inversion

    另外，本文還著重推導了線積分密度分佈和徑向體密度分佈之間的傅立葉積分變換關系，並利用快速傅立葉變換實現了完全拋開abel反演公式的密度反演計算。
  2. Firstly the phase is extracted from interferogram by filtering and displacing frequency spectrum. then the wavefront and the line integral density are recovered by using fft or polynomial fitting method. lastly the radial local density distribution is calculated from the fitting curve of line integral density by the abel inversion

    首先對干涉圖進行頻譜濾波，用頻譜移頻法從干涉圖中提取相位，然後用快速傅立葉變換或多項式擬合實現波面重建，計算線積分密度，再利用abel積分變換從線積分密度的擬合曲線中反演徑向體密度分佈。
